IMPROVEMENT IN HORSE-RAKE S.

Specification forming part of Letters Patent No. 171,419, dated December 21, 1875; application filed October 4, 1875.

To all whom it may concern:

Be it known that I, CHARLES B. PERKINS, of Kenduskeag, in the county of Penobscot and State of Maine, have invented certain new that will enable others skilled in the art to' which it appertains to make and use the same, reference being bad to accompanying drawings, forming a part of this specification, in which- Figure 1 shows a side view of my rake with the wheel in dotted lines; Fig. 2, a side view of levers; Fig. 3, a rear view of same; Fig. 4, a view of clasp or jaw with details.

Same letters show like parts.

My invention relates to certain improve ments in horse rakes, consisting of an improvement in attaching the teeth to the rake, whereby they are unalfected by the elevation or depression of the shafts from any cause; in an improved arrangement of levers for raising the teeth; and in an improved clasp or jaw for securin g them.

Reference to the drawing will illustrate my invention fully.

A shows the axle of the horse-rake, mounted on wheels I), as usual, and supporting a frame, consisting of side pieces 0 c and cross-bar d, to which the shafts are attached. Close to the back part of the axle is secured a rod, 6, ex-

tending its whole length, and upon this rod.

the teeth f are hinged. The effect is to bring the point of connection of the teeth of the rake soclose to the center upon which the axle turns that they are affected very slightly by the motion of the axle around its center, caused by difference in inclination or elevation of the shafts from inequalities of the ground or other reason.

My improved arrangement of levers for raising the teeth from the ground is shown in Figs. 2 and 3. Hinged to the rod 0, at the rear of the axle A, is a forked lever, g, having arms h h, extending outward, and secured to the lifting-bar '5, Supporting the teeth j and arms 70 k and 1, extending downward and backward, respectively. This forked lever enables the power to be applied to the bar 2' at points some distance apart, and obviates any danger of tipping. The manner of its application, having its fulcrum upon the rod on which the teeth are hinged,enables it to raise them with case and rapidity. To operate this forked lever, I employ a bell-crank, hinged to, the cross-bar 01, one end of which, m, serves as a handle by which it may be operated, while the other is attached to a connecting rod, n, which is secured to the arm Z of the forked lever. By pressing back the handle an of the bell-crank lever the connecting rod n is forced down, throwing up the arms h h of the forked lever g, and elevating the teeth with much more rapidity and case than by 'the usual means.

My clasp or jaw for securing the teeth is shown in Fig. 4 and details. It is formed in two parts, 0 p, suffieiently wide at the base or where attached to the rod 6 to keep the teeth the proper distance apart on the rod. Both parts are provided with a semicircular groove, q, to receive the rod 6, and also a second groove, 7', at right angles to the groove q, to receive the tooth. This groove r is terminated bya cavity, 8. The tooth to be inserted is bent over at the end, and the bent portion placed in the cavity. The two parts 0 and p are then placed together and over the rod 6, and the parts are then secured by a bolt or rivet passing through them, holdingthe tooth securely in place, and at the same time allowing it to be readily detached or replaced.

What I claim as my invention, and desire to secure by Letterslatent, is-- 1. The com bination of the lifting-bar i, and forked lever g, havingarms h' h, k is, and Z, and hinged to the rod 0, upon which the teeth are pivoted, as Set forth, for the purposes specified.

2. The combination of the forked lever g, constructed as described, with the bell-crank lever m, and connecting-rod n, as and for the purposes set forth.

3. The improved clasp or jaw for securing the teeth, consisting of two parts, 0 1), provided with grooves q r and cavity 8,. and united and held in place by a bolt or screw, as herein specified.

4. Theimprovedhorse-rake,constructed and In testimony that I claim the foregoing I arranged as herein specified, having its teeth have hereunto set my hand this 28th day of hinged to a rod, 0, directly behind the axle A, September, 187 and Operated by a. forked lever, g, also hinged CHARLES B. PERKINS. to said rod by means of a hell-crank, m, and Witnesses: connecting-rod n, substantially as and for the F. A. H. SC'ACKPOLE, purposes described. I FREMONT H RNE.
